Help Bitcoin (Cash) Great Again

NEWS

2018/08/20: CDY will perform a hard fork upgrade at block height 656960(about September 1st, UTC time). Mining algorithm has been upgraded to deal with the huge hashrate fluctuations. As the mining algorithm will no longer be compatible with ZEC's Equihash algorithm, miners need to upgrade their mining program after upgrade. Links: full-node wallet, mining program.

2018/05/10：CDY will perform a hard fork upgrade at May 15th, this upgrade includes DAA optimization and some features and fixes port from Bitcoin Cash MAY 2018 NETWORK UPGRADE. Details: release note. Please update the node as soon as possible.

2018/04/14：CDY will perform a hard fork upgrade at block height 573123 (about April 20, UTC time). The updated DAA algorithm can deal with fluctuations of hashrate much better. Please update the node as soon as possible.

ABOUT

Among the many questions about bitcoin, the rapid development of quantum computers is like a dark cloud far away from the horizon, which seems distant but disturbing.

Bitcoin Candy team will fork Bitcoin Cash at block height 512666, after which some of the improvements proposed by the community will be added to the forked chain. On this new chain we are going to explore quantum-resistant solution of bitcoin based on our cryptography background.

Only when we put talk into action can we make bitcoin (cash) great again

FAQ

What is CDY?

Bitcoin Candy(CDY) is a new chain forked from Bitcoin Cash at the height of 512666. The original BCH holders will be compensated with 1000 CDY for every BCH held.
New features will be added to the forked chain and we will explore quantum-resistant solution on this chain.

What is quantum-resistant thing?

In the past few years, D-Wave, IBM, Intel and other technological giants invest a lot of manpower and resources to increase research and development of quantum computers, i.e., Google have embedded D-Wave quantum computer into its cloud platform; the research team under Prof. Pan Weijian in Chinese University of Technology have made breakthrough achievements in quantum communications. Under such circumstance, the quantum age will no longer stay in science fiction conjecture (perhaps 5-10 years will come).
The development of quantum computer will not only bring great changes to people's lives, but also pose a serious threat to traditional public key cryptography. Public key cryptosystems such as ECDSA and RSA will be solved in polynomial time by these quantum computers. So, virtual currency like Bitcoin which use ECDSA as a signature algorithm will become unsafe. To find post-quantum digital signature algorithm is of vital important.
Our team has a deep post-quantum cryptography background and will conduct research and experiments on the CDY chain for practical public key signature algorithms in the post-quantum-era blockchain.

Why forked from BCH, can BTC holders get free CDY?

On August 1, 2017, Bitcoin community finally ended its years-long expansion war by splitting the original bitcoin into two chains, Bitcoin cash (BCH) and segwit Bitcoin (inheriting BTC ticker).
We think BCH is more in line with Satoshi Nakamoto's vision of bitcoin "a peer-to-peer electronic cash system" and will have a brighter future.
Only who hold BCH at height 512666(about January 13 ) can get free CDY at the rate of 1BCH : 1000CDY.

What is the total supply of CDY?

CDY will have a total supply of 21 billion, of which 1% will be pre-mined.

How to claim my free CDY?

To get free CDY, you need to hold Bitcoin Cash before height 512666 (about January 13).
1.If your BCH is stored in a wallet where you can control private key yourself, you will definitely get free CDY. Just waiting for the wallet developer to provide feature to claim.
2.If your BCH is stored in the exchange, the exchange will receive free CDY, please pay attention whether the exchange will provide CDY's collection function or not.If the exchange you store BCH does not support CDY, to avoid the loss of assets it is recommended to withdraw BCH to a wallet which you can contral private key or to exchanges that support CDY.
